What blows injector fuses?
I have 55lb low impedence injectors 2.0 Ohm. I dont have my tach harness wired up yet so I dont know the rpms but I pulled thru 2nd gear and it backfired and quit. After an investigation both injector fuses were popped (5a) each. What might be the first place to look? I have them limited to 30%, I have a MSII 3.0 board and running 2.83 code. I am not sure if I hit the rev limiter or not. would that cause this problem? Its on the fuel cut mode. THe wires are are 14 gauge from the injectors all the way to the relay board. Now all I could buy were 7.5 amp fuses so thats whats in there. How big of a fuse can I safely put in there? Are there any settings that could over load the fuses? Thanks Greg

Re: What blows injector fuses?
Lance I have 2 injectors per circut. How do I know when the PWM is optimal? It is at 30% now. I hate to say it but when I started this I was unsure of the thing even running ...now I love it I think I am hooked!
